MS Series 30 kW to 75 kW

Features

High Frequency IGBT-based Switch-Mode Design

The MS Series utilizes the latest IGBT devices to drive down size and increase performance. The high frequency design delivers fast transient response and low output ripple. This performance coupled with Magna-Power's rugged current-fed power processing, enables confidence in even the most demanding applications.

Fully Programmable Power

All MS Series functions and features of are available and programmable from a variety of control methods, including:

Broad Voltage-Current Range, Consistent Controls

Magna-Power Electronics MS Series is built on the same power processing modules as the TS Series, only packaged in a floor-standing cabinet with casters and expanding into higher power levels. The available The MS Series models covers a very wide output range, spanning from voltage levels up to 4000 Vdc (floating) and current levels up to 4500 Adc. Models 30 kW to 60 kW are available in a 38.5” high cabinet, while 75 kW models are available in a 49” high chassis.

Designed for Safety

MS Series power supplies have extensive diagnostic functions, including: phase loss, excessive thermal conditions, over voltage trip (programmable), over current trip (programmable), cleared fuse, and excessive program line voltage. When in standby or diagnostic fault, the AC mains are mechanically disconnected via an embedded AC contactor, providing confidence that the unit is only processing power when desired.

Scalable Master-Slave Operation

For maximum flexibility, all MS Series power supplies can be scaled a in master-slave configuration for higher voltage or current output. Using the plug and play Universal Interface Device (+UID47), units are tied together in via their 37-pin I/O, allowing an increase in system current when configured in parallel or increase in system voltage when configured in series—up to the power supply's output isolation rating.

Extensive Programming Support and Included Software

All MS Series power supplies come standard with a National Instruments LabVIEW™ and LabWindows™/CVI drivers. In addition, an IVI driver is included supporting Visual C++, Visual C#, Visual Basic .NET, MATLAB, Measure Foundry, PAWS, Visual Basic 6.0, and Agilent VEE Pro. A Standard Commands for Programmable Instrumentation (SCPI) command set is also supported, allowing programming using raw ASCII commands. Finally, Magna-Power's RIS Panel software is provided allowing for a virtual control panel controlling the power supply via any of the available communication interfaces.

Models

There are hundreds of possible configurations for the MS Series product. Using the following ordering guide and models chart to define the best model for your application. Need less power? Visit our TS Series product line. Need more power? Visit our MT Series product line.

Models Chart

The following chart details the available standard MS Series models. The Current Maximum (Adc) column is separated by the available power levels. To determine the appropriate model, first select your output Voltage Maximum (Vdc) to find appropriate row. Next, select one desired Current Maximum from the row that contains your desired Voltage Maximum. Then, construct your model number according to the model ordering guide, above. Non-standard voltage and current configurations are available.

Options

The following options are available for the MS Series programmable DC power supply:

High Isolation Output
Available for models rated for 250 Vdc to 1000 Vdc, the +ISO option extends the output isolation, used when the application demands floating or tying units in series beyond the standard 1000 Vdc output isolation rating. More

High Slew Rate Output
The high slew rate option is a control modification and replaces the standard output stage with one of low capacitance film and/or aluminum electrolytic capacitors, capable of high RMS currents. This stage provides higher bandwidth with faster output rise and fall times.More

IEEE-488 GPIB Interface
Full control of the product's features and diagnostics over a IEEE-488 GPIB interface. The GPIB interface allows up to 15 devices may be connected to one bus and is compatible with all Magna-Power provided software and drivers. More

The Integrated Blocking Diode Option (+BD) provides an internally heat-sunk protection diode on the positive output terminal of a MagnaDC programmable DC power supply to protect the product's output from reverse voltage up to 1200 Vdc.

LXI TCP/IP Ethernet Interface
Full control of all the product's features and diagnostics over a LXI Class C Certified TCP/IP Ethernet interface. Includes an embedded web server and compatibility with all Magna-Power provided software and drivers. More

The RS-232 to RS422 or RS-485 converter is an external industrial accessory to convert the power supply's standard RS-232. Unlike converters which require programming hardware handshaking signals to control RS-485 or RS-422 operation, the +RS485 option provides automatic control.

The UID47 accessory eases master-slave parallel or series configuration of Magna-Power DC power supplies, enabling near equal current or voltage sharing, depending on the configuration. The accessory includes the UID47 with integrated circuitry and (2) 6-ft DB37 cables.

Water Cooling
Water cooling is available instead of the standard air cooling. Water cooled units are fully enclosed and to not take in any external air, making them ideal for corrosive environments, densely packed cabinets or setups where water is readily available. More
